PILZ PNOZ mm0.1p 772001 Configurable Safety Relay

The PILZ PNOZ mm0.1p (order number 772001) is a base unit for the PNOZmulti Mini range of configurable safety relays. It provides 8 digital inputs (safe), 2 semiconductor outputs (safe), and 2 relay outputs (safe) for safety functions such as emergency stop, safety gate, light curtain, and two-hand controls. The unit is programmed via the PILZ PNOZmulti Configurator software.

Technical Specifications

Supply voltage: 24 V DC (-15% / +20%). Power consumption: 2 W typical. Inputs: 8 dual-channel capable, 24 V DC, with cross-circuit detection. Relay outputs: 2 NO contacts, 6 A at 230 V AC, mechanical life 10^7 cycles. Semiconductor outputs: 2 PNP, 24 V DC, 2 A each, short-circuit protected. Safety integrity level: SIL CL 3 (IEC 62061), PL e (EN ISO 13849-1). Response time: 20 ms (typical).

Configuration and Programming

Programming requires the PNOZmulti Configurator (PC software, free download). The base unit is connected via a mini-USB port. Users drag and drop function blocks (e.g., emergency stop, guard locking, muting) onto a virtual circuit. Up to 8 expansion modules (e.g., PNOZ mm0.2p input, mm0.3p output, mm0.4p relay) can be added to increase I/O count. Configuration data is stored on a removable chip (memory card) inside the unit. No soldering or wiring changes needed for logic updates.

Diagnostics and LED Indication

Six LEDs: Power (green), Run (green), Fault (red), Input status (yellow, 4 LEDs shared via multiplexing). Detailed error messages (e.g., channel discrepancy, supply error) are viewable in the software’s online diagnostics. The unit logs the last 10 safety events with timestamps (power-on hours). A restart interlock can be configured to require a manual reset button after power restoration.

Environmental and Mounting

Operating temperature: -10°C to 55°C. Storage: -40°C to 85°C. Humidity: 93% non-condensing. Protection: IP20. Mounting on 35 mm DIN rail (EN 60715). Dimensions: 45 mm x 100 mm x 120 mm. The housing is green for safety identification. Vibration resistance: 5 g (10–150 Hz). Certifications: CE, cULus, TÜV, CCC.

Typical Applications

Used in automotive assembly stations, packaging machinery, robot cells, and conveyor systems. The configurable nature allows one base unit to replace multiple dedicated safety relays, reducing cabinet space. The PNOZ mm0.1p can directly monitor OSSD outputs of a light curtain without external converters.
